## Motion Ratio Formula

The following formula is used to calculate the Motion Ratio.

**MR = dS / dW**

- Where MR is the Motion Ratio ( )
- dS is the change in shock position (in)
- dW is the change in wheel position (in)

## How to Calculate Motion Ratio?

The following example problems outline how to calculate Motion Ratio.

Example Problem #1:

- First, determine the change in shock position (in).
- The change in shock position (in) is given as: 2.5.

- Next, determine the change in wheel position (in).
- The change in wheel position (in) is provided as: 4.

- Finally, calculate the Motion Ratio using the equation above:

MR = dS / dW

The values given above are inserted into the equation below and the solution is calculated:

MR = 2.5 / 4 = .625

Example Problem #2:** **

For this problem, the variables required are provided below:

change in shock position (in) = 4.5

change in wheel position (in) = 7

Test your knowledge using the equation and check your answer with the calculator above.

MR = dS / dW** = ?**
